There are only a few decent sources for links some are free
and some are not, some have limits unless you have a paid
account:

Opensitexplorer (Moz)

ahrefs

MajesticSEO

Blekko API

Searchmetrics

And if you own the site:

Google Webmaster Tools

Bing Webmaster Tools Links Data (Formely known as Yahoo Searh
link:) the hidden gem in Bing is it gives you a full csv dump...

The other is using Scrapebox with uts built in proxys to do a
link: scrape on old search engines.

I dont see the use of Xenu for scraping backlinks, theres far
too many other tools out there for that, also xenu is used by
SEO'ers though its primary goal from what i can see is for
crawling sites and QA.

I still didn't understand your
report, however this time I looked
into the code. Xenu actually
launches three (!) URLs and one of
them is broken, because yahoo
discontinued the service. I
removed it. I there anyone here
who knows another useful backlinks
service?
